Replacing Double Glazed Units

Double-glazed units can be replaced to reduce the loss of heat and noise and also reduce heating costs. Modern coatings and argon/krypton gas filled units make them extremely energy efficient.

The new unit, crafted according to precise measurements, awaits its place and calls for care and precision. This is the moment that will stop the world and puts your work into perspective.

Take the old unit out of the way

The removal of the old unit is a crucial step to ensure the new double-glazed window is built to precise measurements. Carefully clean the frame of any dirt, dust or old sealant, and then repair any damage that could be present. Sanding and wood filler can be used to repair minor damage however, major damage might require professional assistance.

After the glass has been removed, it is essential to determine its width, height and thickness. The most effective method to do this is by prising out the glazing beads that hold the unit. This is a delicate task that requires patience and prudence. It is recommended to take your time and always wear safety equipment to protect yourself from unexpected shards of glass and accidental slips.

Start by removing the top of the glazing strip using a sharp chisel, or a wide-bladed, sharp screwdriver. It is best to ask someone to hold the window unit as you remove all the beads. The unit could fall from the frame and break.

After removing all the beads, it is crucial to determine the width, the height and the thickness of the present unit. The measurement data to accurately build a replacement unit. It will also serve as a guideline to ensure that the new unit is constructed to fit the frame. It is crucial to make sure that the window is properly fitted since a mismatch could not only require the entire unit to be disassembled and reassembled but will also affect the performance of the unit. This is particularly relevant in Australia as our homes are often exposed to extreme weather conditions.


Preparing the Frame

If you are replacing a fixed window, or a sliding door with an opening or fixed sash, make sure the new unit is the right size. UPVC frames have very little movement and double-glazed sealed units that is a few millimeters larger than the original is not going to fit. Be sure to measure carefully, and consult a professional or the manufacturer's guide in order to make sure you get accurate measurements.

When you have a clear idea of the dimensions of the replacement and you are sure it is correctly fitted remove the glass from its frame. Be sure to work in a well-lit space and wear protective equipment like gloves to prevent injuries from glass shards. Use a putty blade to pry off the glazing strips or beads that secure the glass into the frame, and remove them from the perimeter of the pane. Avoid slipping on the glass or straining frame.

Make sure the frame can open and close smoothly when the new sealed double-glazing unit is installed. It should be a tight fit, but you can alter this if needed by adding or removing packing. For double glazing seal repairs , if your frame is a sliding door, you may have to add extra packers at the top of the hinge and at the opposite corner to keep the sash from catching or shaking when it opens.

Finally, clean the frame and take off any old sealant or glazing tape, as needed. Assess any damage, and make minor repairs, if needed, using wood filler or sanding. The frame will be refreshed by a final cleaning and inspection and will be able to endure the harsh Australian weather for many years.

Lifting the New Unit

Over time, double glazed sealed units (or a sealed unit as it is often known) may develop issues like moisture between panes and/or misting. This can reduce the efficiency of your windows and allow cold air to enter and warm air from your heater to escape, which can result in uncomfortable energy bills and discomfort.

This kind of seal failure typically occurs due to aging general wear and tear, or harsh chemical cleaners that deteriorate the sealing material. Sometimes however, the cause can be traced to the shrinking and expanding of the glass due to temperature changes and seasonal changes.

After the frame has been cleaned and prepared, you can start lifting the frame into place. This is an exciting step because you've made a significant improvement to your home, improving its comfort in the winter months and cooling it in summer, and helping to reduce your energy bill.

It is essential to ensure the new unit is properly fitted in the frame prior to locking it to the frame. A little bit of care during this stage can prevent damage to the frame, and also the glass.

If your windows have glazing tape or sealant, now is the time to apply a small bead around the perimeter of the glass and frame to create a solid barrier against moisture and air infiltration. Make sure to tighten the sealant carefully, but not so tightly that it strains the frame or glass. Then, give yourself a pat on the back for an excellent job, and then enjoy your newly-installed double-glazed window!

Secure the Unit

This is the time when the work is done. The unit will be firmly set in the frame and a new sealant will be applied around its perimeter. The unit is now secure to withstand Australia's varied weather conditions, a guarantee for warmth in winter and cooling in summer. It's the moment when you can confirm the accuracy of your measurement and removal, which is a proof of a unit crafted to exact measurements.

It is important to find the perfect balance between securing the unit and not stressing the glass. If it's too loose, the unit may lose its airtight seal. If it's too tight, it may cause damage to the frame or weaken the material. Each screw must be put in its initial position and turned to just the right amount to ensure that the unit is held securely without putting pressure too high.

This is the final stage in a project that will increase the energy efficiency of a house, comfort, and appearance. With the new double-glazed unit sitting snugly in the frame and securing an all-new layer of sealant around the perimeter, this is the moment that signifies the end of your work.

The cavity between the glass panes is filled with argon or a desiccant. Argon, unlike air has a lower thermal conductivity which reduces heat transfer. Desiccants also help to absorb moisture from the air, which prevents mould and condensation in the frame. The spacer bar is constructed of aluminum and is an essential component of the insulation system. The aluminum blocks the transfer of heat but also keeps the edge of the insulated glass warm to avoid condensation.

Verifying Your Work

After you've put in the new unit and put an ounce of silicone sealant around the edges it is essential to leave it alone to set - don't handle it! It will take at least four hours for the silicone sealant to reach its maximum strength and form an impenetrable wall. While you wait, visually examine your work to determine whether there are any gaps or issues that could affect the effectiveness or appearance.

It is also a great opportunity to check the seals and frames to determine if there are any signs of damage, and determine if the whole window needs to be replaced. A faulty seal will affect the efficiency of your home's energy usage, causing drafts or cold spots. It also lets UV rays enter the home which can cause furniture to fade, and carpets and curtains to wear more quickly.

If you're experiencing any of these problems, it is a sign that your double glazing is in need of replacing. Taking care of it quickly will lower your energy costs and provide a more comfortable, relaxed home environment.

It is a complex and labor-intensive job that requires the appropriate equipment, precise measuring and careful preparation. It is not an DIY project and should be handled by a specialist who has experience with uPVC Windows and Doors. They can ensure that the new unit is installed correctly to shield your home from the elements. Their expertise will ensure that the double-glazed unit you choose is both efficient and quiet, providing warmth in the winter months and cooling in summer. This will shield your home from weather damage.
